(2d2 + 3d + 4) y = x2 - 2x

Answer»

Simplifying

(2d2 + 3d + 4) * y = x2 + -2x

Reorder the terms:

(4 + 3d + 2d2) * y = x2 + -2x

Reorder the terms for easier multiplication:

y(4 + 3d + 2d2) = x2 + -2x

(4 * y + 3d * y + 2d2 * y) = x2 + -2x

Reorder the terms:

(3dy + 2d2y + 4y) = x2 + -2x

(3dy + 2d2y + 4y) = x2 + -2x

Reorder the terms:

3dy + 2d2y + 4y = -2x + x2

Solving

3dy + 2d2y + 4y = -2x + x2

Solving for variable 'd'.

Reorder the terms:

3dy + 2d2y + 2x + -1x2 + 4y = -2x + x2 + 2x + -1x2

Reorder the terms:

3dy + 2d2y + 2x + -1x2 + 4y = -2x + 2x + x2 + -1x2

Combine like terms: -2x + 2x = 0

3dy + 2d2y + 2x + -1x2 + 4y = 0 + x2 + -1x2

3dy + 2d2y + 2x + -1x2 + 4y = x2 + -1x2

Combine like terms: x2 + -1x2 = 0

3dy + 2d2y + 2x + -1x2 + 4y = 0

The solution to this equation could not be determined.
